MBK Digital Q&A AI Used at Mitsui & Co. Shareholders Meeting
The design shows where corporate AI is landing first: not in generating shareholder answers but in recall and document search under pressure, with a person keeping final judgment.

MBK Digital developed an AI system that supports Q&A at shareholders meetings, and it was introduced at Mitsui & Co.'s shareholders meeting in June 2026. Rather than generating answers, the system presents expected Q&A and materials related to a question by semantic search, averaging about 1 second. It ingests Microsoft Word and Excel documents in block units, registers screened QA in a vector database, and leaves the final answer to the respondent.
The system reverses the usual setup. When a question is entered, the AI does not draft reply text. It searches anticipated Q&A and related materials that have already been checked and organized, then presents the matches for the respondent to read while composing an answer in their own words.
MBK Digital describes the design as an "AI that supports judgment" rather than an "AI that gives answers." Materials created in Word and Excel are processed in block units, and screened QA is registered in a vector database and searched by semantic closeness to the question. Results arrive in about 1 second on average.
